theres a lot to comb through in here and this may have been answered somewhere but im going to ask anyway...
i own a '90 GTA with the stock 16" mesh wheel. i'd like to step up to a 17" wheel to clear some future brake mods. i know there is a 20 mm offset difference front to rear on my car since it has the 9 bolt... i really like the torq thrust II (i know i know, outmoded, overused blah blah ) but im not sure what bs/width will fit.
i want to get the max footprint i can in the back, got some mods on the engine/driveline that the old 245's just cant hook anymore. the car has eibach sportlines so about 1.5" drop, i'd like to avoid rubbing as much as i can. i dsilike wheel spacers but if someone has a max width on the torq thrust/spacer combo i'd love to hear any input. (want to coat the centers gold to stay with the flame red/gold badging theme)

 

also a good combo for the front that doesnt rub at lock would be great, car is set up for twisties not straights so would like to increase front grip too if i can

 

hmmmm not even a hater saying "why you want torq thrusts" yet...

 

The offset on the fronts is 16mm. I don't mind the wheels you want, I see them more on Camaro's than TA's so get them if you want. What I would do is make sure to get the same -16 offset on all the wheels or at least -16 on two of them and maybe more on the other two if you want that wider stance on the rear. I have my wheels flipped with a 1/4" spacer in the front and it looks killer, the rears don't stick out really, but looks mean and correct. I that deeper look in the front just looks dumb to me.

 

Both incorrect. The offset for the factory wheels in the front is 0mm and the rear is 16mm. You can put 0mm offset wheels on all four corners. Doing this will actually make the rear track wider than the front and your car will handle better.

 

thanks for the correction, yeah rear wheels are offset 16 mm. what im looking to find out is if anyone has maxed the wheel/tire combo in one of these cars with that wheel and drop, and if so what wheel/tire size and what spacer if any is needed. id also prefer not to roll fender edges since this car is immaculate and i dont want to do anything that cant be fairly easily undone

 

no input? anybody?

 

torque thrust M's lol

 

Pick what brakes you want to run first, then order wheels. Where in MI are you?

17x9.5 with 5.5" backspacing is pretty standard. I have 6.0" backspacing up front with 1/2" spacer to clear the big brakes.

 

LOL THAT is the car that made me want to do the torq thrusts! looks great. i think i want to run the baer black label 13" kit on the front. i gather that with the hub adapter it pushes the wheel out a little bit. my main concern was with the rear, since it has the offset wheel. does your car also have the 9 bolt?

 

[QUOTE=scholtmj;5538642]Pick what brakes you want to run first, then order wheels. Where in MI are you?

I'm about 15 min south of Lansing

 

Yes my car has the 9-bolt but it's the same width as the 10. I assume you're talking about the black label kit that Hawks sells? With those brakes you could fit 17x9.5 all the way around with 5.5" backspacing on each wheel.

 

yup thats the kit im talking about i'd like to step up to maybe an 11" wheel in the rear if i can, the mods i have planned for the engine are going to need as much rubber as i can get without getting crazy and cutting stuff up and even with the mild mods i have right now the 245's dont stick for crap. i see youre in grand rapids, not too far! curious how much room you have left inside/outside with the 9.5's

 

i want those exact rims you have on my gta... I want to run 245 up front and 305-315 tires in the back.....

 

Spare room front or rear? The fronts rub slightly on full lock - the rears clear everything. I could not put the 6.0" bs wheels on the rear because the parking brake cable got in the way and I didn't care (6.0" bs wheels are for the front). I'll have to fix the cable when I put 17x11s on the rear this summer.

 

i meant extra room in the rear. be interesting to see what you come up with

 

Rears are 17x11 with 7" back spacing. Take a 17x9.5 with 5.5" back spacing and add the extra width on the inside.

 

awesome thanks for the info... now to get some wheels ordered one of these days... then find a good powdercoater to do the centers in gold...
